Question 20

The connection between bone and bone is disrupted when a ligament is torn.

A torn ligament disrupts the connection between two bones, as ligaments serve to connect bones at joints, providing stability and support.

A) Bone to bone

This option is correct because ligaments are connective tissues that specifically bind bones together at joints. When a ligament is torn, the structural integrity between the connected bones is compromised, leading to instability and potential joint dysfunction.

B) Muscle to nerve

This option is incorrect as it describes a relationship that is not relevant to ligaments. Muscles are connected to bones via tendons, while nerves transmit signals to and from muscles, but they do not connect directly to ligaments or bones.

C) Bone to artery

This option is incorrect because arteries are part of the circulatory system and do not connect directly to bones. Ligaments have no role in connecting bones to arteries; rather, they connect bones to other bones.

D) Muscle to bone

This option is incorrect since muscles are connected to bones by tendons, not ligaments. A torn ligament does not disrupt the muscle-to-bone connection, but rather the bone-to-bone connection.

Conclusion

The correct answer is A) Bone to bone, as it accurately identifies the relationship disrupted by a torn ligament. The other options fail to represent the function of ligaments and their role in joint stability, confirming that they are not relevant to the context of the question.
